Throwout Bearing Question
The car is a MY98 2.5 RS
Does anyone know what metal 1. the throwout bearing and 2. the shaft it runs along are made of?
Thanks!

The shaft the throwout bearing (I believe it's stainless by the way) is the transmission snout. Made out of the same thing the tranny case is made out of, aluminium. I am very curious why you ask, please do tell...as this issue just came up at the shop, and well, we have a part

Hi Ryan
Thanks for the reply. The reason I asked the question is because of an on going issue I have with the clutch action. See the thread below for a complete description.

I'm wondering if the T/O bearing has worn a groove, and is sticking, on the shaft.
If this makes sense to you, or if you can shed any more light on this situation, I'd be very appreciative of your input!

Did the dealership grease up the short outer shaft that the TO bearing slides along? If not it should be. It doesn't take much grease to reduce the friction. Also make sure they check to see if the metal hook/tabs on the TO bearing are not cracked or broken. Its not unheard of to have these crack or break on you. If they do the bearing will turn slightly and put more pressure on one side then the other. That is if it doesn't come off the fork completely. Those are a couple ideas of things to look for. If the TO bearing has worn a groove in that shaft then you need a new casing cause that shaft is part of the casing to the transmission.

Read my posts in this thread, that should give you the backround of the problem.

This is more or less true (for 800 bucks), but like I said, we have a part
To sum it all up, after spending a day over at PDM (www.pdmturbos.com) feeling the snouts on misc. trannies I am convinced that not one Subaru tranny is without the grooves in the snout. Although your discription is interesting in the way the clutch feels as if it's sticking, the fix was developed mainly to ward off shudder/chatter. The theory is that the clutch is wobbling causing uneven contact on the flywheel which furthers the problem until it finally settles down. Marks and scuffs on many used flywheels supports this theory. But I could imagine your discription is also caused by the grooves. Hmmm, lot of bad grooves goin' on around here!!!
Anyway, I have the part (see Nasioc Post). I'm doing my best to test it's limits, and so far so good. If I can't break it, no one can

I still don't understand why the clutch shudder and worn shafts seem to be a US thing. I've seen alot of WRXs including some 1993 models while I was in Japan and never heard of anything like that happening even on a high mileage car. Especially given that a TO bearing in the US costs more then a $100 and in Japan it was like $40.

I have a bud here that has a 98 that has frequent problems with T/O bearings we thought, It turned out it has something to do with the shift fork and not the T/O. You might want to inspect it the next time you can.
